Revealing mistakes: During the negotiations to buy Bo-Tat the insignia on Doyle's beret is reversed. The insignia is of the 5th Special Forces Group and is a diagonal yellow stripe with three scarlet stripes in it going from the top left (as seen by the observer) to the lower right.) Doyle's is going top right to lower left. (NOTE: It happens that the Vietnamese flag is yellow with three horizontal red stripes.)
